Over the coming weeks we are revisiting the top fantasy seasons of the PFF era (i.e. since 2007), and up first is the wide receiver position. In case you missed it, we kicked off the series earlier this week with Nos. 11-20. Today, we’ll count down the top-10 fantasy WR seasons.

PFF Glossary

PPO: points per opportunity, defined as carries + pass routesYPRR: yards per route run, i.e. a more useful metric than the standard yards per receptionRTG: passer rating when targetedADOT: average depth of target.

In 2012, Marshall finished second in PPR scoring behind only Calvin Johnson, who turned in a historic season (more on him in a bit). However, Marshall led all wideouts with 0.61 fantasy points per opportunity that year, or, a whole 36-percent more than Johnson’s PPO.

Of course, the two were separated by only five catches, but Marshall’s 11 TDs were more than double that of Johnson’s five. Marshall’s target share and production that year no doubt factored into some of the fantasy hype surrounding DeVante Parker when Jay Cutler landed with Miami this past season, given their similar build and athletic profile. However, greatness is not so easily replicated.
